class Bundler::RemoteSpecification
Represents a lazily loaded gem specification, where the full specification is on the source server in rubygems' “quick” index. The proxy object is to be seeded with what we're given from the source's abbreviated index - the full specification will only be fetched when necessary.

Compare this specification against another object. Using #sort_obj is compatible with Gem::Specification and other Bundler or RubyGems objects. Otherwise, use the default Object comparison.
# File lib/bundler/remote_specification.rb, line 40 def <=>(other) if other.respond_to?(:sort_obj) sort_obj <=> other.sort_obj else super end end
Because Rubyforge cannot be trusted to provide valid specifications once the remote gem is downloaded, the backend specification will be swapped out.
# File lib/bundler/remote_specification.rb, line 51 def __swap__(spec) raise APIResponseInvalidDependenciesError unless spec.dependencies.all? {|d| d.is_a?(Gem::Dependency) } SharedHelpers.ensure_same_dependencies(self, dependencies, spec.dependencies) @_remote_specification = spec end
# File lib/bundler/remote_specification.rb, line 75 def dependencies @dependencies ||= begin deps = method_missing(:dependencies) # allow us to handle when the specs dependencies are an array of array of string # in order to delay the crash to `#__swap__` where it results in a friendlier error # see https://github.com/rubygems/bundler/issues/5797 deps = deps.map {|d| d.is_a?(Gem::Dependency) ? d : Gem::Dependency.new(*d) } deps end end
Needed before installs, since the arch matters then and quick specs don't bother to include the arch in the platform string
# File lib/bundler/remote_specification.rb, line 25 def fetch_platform @platform = _remote_specification.platform end
# File lib/bundler/remote_specification.rb, line 29 def full_name if platform == Gem::Platform::RUBY || platform.nil? "#{@name}-#{@version}" else "#{@name}-#{@version}-#{platform}" end end
# File lib/bundler/remote_specification.rb, line 88 def git_version return unless loaded_from && source.is_a?(Bundler::Source::Git) " #{source.revision[0..6]}" end

Create a delegate used for sorting. This strategy is copied from RubyGems 2.23 and ensures that Bundler's specifications can be compared and sorted with RubyGems' own specifications.
@see #<=> @see Gem::Specification#sort_obj
@return [Array] an object you can use to compare and sort this
specification against other specifications
